Abstract

Converting discreet narrowband filter radiometer irradiance measurements into continuous allows the construction of weighted doses such as an erythemal and plant action spectra. Synthetic spectra were retrieved from 7 UV narrowband channels using a fast 5 parameter fit. The synthetic spectra are compared with measurements from a collocated spectroradiometer and the erythemally weighted doses from the synthetic spectra are compared with daily erythemal doses from a collocated broadband radiometer. The agreement in spectral data ranges generally from 0.75 to 1.25 depending upon wavelength and solar zenith angle. Agreement between daily erythemal doses are generally between 0.70 and 0.90.
